Importance of backup in system administration:
Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.
Three methods for performing backup:
- Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.
- External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go.
- Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.
Answer:
Number of feet in a mile
Explanation:
In this problem, we need to find an option that to be created as a constant variable.
In option (a) "number of feet in a mile".
As 1 mile = 5280 foot
The number of feet in a mile is constant in every condition.
In option (b), (c) and (d)
number of people inside a store
, current grade in a class
, score in a football game are no fixed. It is not created as a constant variable.
Hence, the correct option is (a).
Answer:
The modified program is as follows:
user_input = input()
short_names = list(user_input.split(" "))
short_names.pop(0)
short_names[-1] = "Joe"
print(short_names)
Explanation:
This gets the user input
user_input = input()
This converts input to list
short_names = list(user_input.split(" "))
This removes the first item of the list
short_names.pop(0)
This updates the last item to "Joe"
short_names[-1] = "Joe"
This prints the updated list
print(short_names)
Blogs, even academic and professional, are not usually considered reliable sources. Most importantly, that's because they don't undergo the peer review process, which ensures the quality of the published papers (that they don't publish lies, in simple words).
So usually, you would prefer a published paper.
When then would you use a blog?
One such instance is when you want to find out about a quickly changing field , for example the newest standards in software development. So software engineering is one such field.
Another field is internet protection and security, as the viruses and the ways to defend against them also develop faster than can be published in a paper
